A football team has a net yardage of −38 1/3
yards on a series of plays. The team needs a net yardage of 20 yards to get a first down. How many yards do they have to get on their next play to get a first down?
well how do you find x?
To determine how many yards the team needs to get on their next play to get a first down, we need to subtract the current net yardage from the desired net yardage.
The current net yardage is given as -38 1/3 yards, and the desired net yardage is 20 yards.
To subtract a fraction from a whole number, we first need to convert the whole number into a fraction with the same denominator as the fraction we are subtracting. In this case, we can convert 20 into a fraction with a denominator of 3:
20 = 20/1
Next, we can subtract the two fractions:
20/1 - 38 1/3
To subtract the fractions, we need to find a common denominator. In this case, the common denominator is 3:
20/1 = 60/3
Now we can subtract the fractions:
60/3 - 38 1/3 = (60 - 38)/3 - 1/3 = 22/3 - 1/3 = 21/3 = 7
Therefore, the team needs to gain 7 yards on their next play to get a first down.
-38 1/3 + x = 20
Now just find x.
